DLL search-order/planting in the TeamViewer Remote Management Monitoring installer for Windows before 26.10.1 lets a local authenticated low-privileged user plant a malicious DLL that is loaded with elevated privileges when a higher-privileged user runs the installer, yielding arbitrary code execution. Exploitation requires an existing foothold on the host plus user interaction, and no public exploit is identified at time of analysis. Vendor patch 26.10.1 resolves the condition; the assessed priority is this_week, a genuine but not emergency-grade issue.
Local privilege escalation in TeamViewer Remote Management Monitoring for Windows before 26.10.1: a low-privileged authenticated local user can impersonate the IPC broker and cause the Monitoring service to execute arbitrary code as NT AUTHORITY\SYSTEM. Only hosts with the Remote Management Monitoring component installed and its service running are affected (base TeamViewer remote-access installs without the Monitoring module are not indicated as affected by available data), and exploitation requires an existing low-privilege local session (CVSS:3.1/AV:L/AC:L/PR:L/UI:N). This is a credible but non-emergency issue - no public exploit code or active exploitation is confirmed, and the vendor has released a fixed version (26.10.1).
Local privilege escalation in TeamViewer Full Client and Host (prior to 15.83) and the Remote Management - Monitoring component (prior to 26.10.1) allows an authenticated low-privileged local user to execute scripts as SYSTEM/root by abusing improper access control on the IPC channel between the client/host and the monitoring component. Rated CVSS 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), successful abuse gives full confidentiality, integrity and availability impact on the affected host, but requires the attacker to already hold a valid low-privileged local account and presumes the Remote Management - Monitoring component is deployed. No public exploit code has been identified at time of analysis and the CVE is not in CISA KEV; vendor-released fixes exist (15.83 for current Full Client/Host branches, 15.64.10 for legacy Windows 7/8 builds, and 26.10.1 for Remote Management - Monitoring) per TeamViewer bulletin TV-2026-1012.
